UNITED STATES JAMES R. FLEMING, OF SCRANTON, PENNSYLVANIA.

JOURNAL BOX AND MOUNTING.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed February 18, 1920. Serial No. 359,588.

To all whom 2'2. may concern Be it known that I, James R. FLEMING, a citizen of the United States, and a resident of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Journal Boxes and Mountings, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to permit wheels and axles therefor to follow the ir regularities of the track on which the wheel rides, independent of the movement of the car body; to permit the use of a friction reducing bearing of the rolling members type, to fit closely the axle on which it is mounted, and to rise and fall in correspondence with the idiosyncrasies of the track on which the wheel is moving, said rise and fall being independent of the riding position of the body of the car; to permit the use of friction reducing bearings on springless car bodies to permit the easy removal of axles equipped with wheels and bearings of the character mentioned from service relation; and to regulate and limit the movement of the axle and parts associated therewith.

Drawings:

Figure 1 is a side View of a journal bearing and mounting therefor, said journal and mounting being constructed and arranged in accordance with the present invention;

Fig. 2 is a. similar view showing a modified form thereof;

Fig. 3 is a similar View showing the further modification of the invention;

Fig. 4 is a similar view of'another modified embodiment of the invention; and

Fig. 5 is a similar View showing the invention as embodied in a further modified form, together with a modified form of the mounting chair.

The particular service for which the axle journals herein disclosed is designed is that for'mine cars, generally employed in coal mines. In these cars it is impractical and undesirable to have carrying springs for one reason in particular, to. wit, the undesirability of raising the car body more than necessary. For this reason the chair 10 is bolted direct to the car sill or bolster 11. The chair forms a wearing surface for the barrel casing of the friction reducing hearing, such as the casing 12 of a roller bearing of any desired type.

To prevent the disadjustment lengthwise of the casing and the axles contained therein, each casing is provided with one or more extension fins 13, the outer edges of which are juxtaposed to and parallel with the vertical inner surfaces of the guide brackets 14. The brackets 14 are extended down from the body of the chair 10, and are integrally formed therewith by being cast in the same mold.

lVhile the brackets 14 may be constructed as shown in Fig. 1 of the drawings, 1, nevertheless, prefer to provide one or more of the brackets at the lower ends thereof with bench-like flanges 15. The flanges 15 serve to engage the lugs 13, when the casing 12 is lowered. The flanges 15 thus serve the double purpose of guiding the casing 12 and of preventing the separation thereof and of the axle and wheel associated therewith when the car is lifted bodily off the track and out of service position.

As shown in Fig. 2 of the drawings, both brackets have the extensions 15. The modification shown in Fig. 3 of the drawings is that wherein the chair 16 is changed from the form indicated by the numeral 10 to one having the flange 15 on one side only of the box, while at the opposite side bolt perforations 17 are formed in the end walls 18 to receive supporting bolts 19, which serve to lock the casing 12 in position when the car body is lifted clear of the ground, the weight of thecasing 12 and parts associated therewith then resting on the extensions 13 and the lugs 15 and bolt 19.

lVith the construction such as shown it is possible to dispose the casing 12 so that the rise and fall of said casing and parts associated therewith is negligible. Such would be the case if the bolt 19 were placed in the perforation 17 adjacent the fin 13 when in the position shown in Fig. 3.

It is obvious that when employing the bolt 19 for supporting one side of the casing 12, the said casing may be readily removed from service by withdrawing the bolt 19 which will permit the fin 13 of the said casing to drop freely from engagement with the chair16. Also it is obvious that the flange 15 at the opposite side of the said chair being in raised position forms a contracted chamber for the fin 13 associated therewith. A hinge-like structure on which the casing 12 rocks when the wheel and axle associated therewith rises and falls in corf rest on said casing; meansassociated with respondence with the road bed is thus formed.

In Fig. 4: of the drawings an inversion of the form shown in Fig. 3 is illustrated. The hinge in the structure shown inFig. 4: is provided with a suspension bolt 20, which extends through perforations in the hinge lug 21, and the drop support 22. The fin 13 at the opposite side of the casing 12 is engaged in its lower position by the flange 15 of the bracket 14. Between the flange l5 and a shoulder formed on the bracket a space ifs provided, in which the fin may rise and all.

It is obvious that the casing 12 and parts associated therewith, when provided with this form of mounting may be quickly and readily installed in and removed from service', it being only necessary to insert or withdraw the bolt 20.

When employing a chair such as indicated by the numeral 24:, in Fig. 5 of the drawings, the journal and mounting therefor may be removed by withdrawing the bolts 25, to this end loosening the nuts 26 in the upper side of the bolster 11.

In all the forms shown it will be observed that the fins 13 serve to maintain the transverse alinement of the casing 12'and of the axles associated therewith. Also it will be noted the construction of the bearing casing and the mounting therefor is simplified and strengthened while permitting the removal of the casing from the chair on which it has usually a service bearing.

Claims:

1. A structure as characterized comprising a cylindrical bearing casing; a chair for said casing; means associated with said chair for maintaining the transverse alinement of said casing and parts associated therewith vwhile permitting the movement of said casing to and from said chair, said means embodying a plurality of vertical guide walls extending from said chair; and means associated with said guide walls for limiting the separation of said casing from said chair.

2. A structure'as, characterized comprising'a cylindrical bearing casing; a chair to said chair for maintaining the transverse alinement of said casing and parts associated therewith while permitting the'mo'vement of said casing to and from said chair, said means embodying a plurality of vertical guide walls extendingfrom said chair to limit the movement of said casing lengthwise of said chair; and means associated with said guide walls for limiting the movement of said casing to and from said chair,

said means embodying a flange integrally formed with said walls for engaging said casing when removed a predetermined dis tance from said chair.

3. A structure as characterized comprising a cylindrical bearing casing closely fitting an axle, said casing having laterally extended guide fins; a chair for said casing, said chair having pendent guide members for engaging said fins to limit the separation of said casing and said chair in service.

at. A structure as characterized comprising a cylindrical bearing casing for closely fitting an axle, said casing having laterally extended guide fins; a chair for said casing, said chair having pendent guide members adapted to engage said fins to limit the separation of said casing and said chair in service; and means cooperating with said fins for forming a hinge-like connection with said chair and the pendent walls thereof.

5. A- structure as characterized comprising a cylindrical bearing casing fitting closely a vehicle axle; a chair therefor and means pivotally connecting said chair and said casing at one side of the center of said casing to permit said casing and axle associated therewith to move to and from said chair.

6. A structure as characterized comprising a cylindrical bearing casing fitting closely a vehicle axle; a chair therefor; means pivotally connecting said chair and said casing at one side of the center of said casing to permit said casing and axle associated-therewith to move to and from said I pivotally suspending said casing ,on said chair, said means embodying a plurality of hinged lugs extending from said chair and said casing, and a hinge bolt extending therethrough; and a bracket integrally formed with said chair at the opposite side of said casing for determining the extent of the movement of said casing.
